To use cellular data on a laptop, you connect the laptop to the internet through either a built-in cellular modem with a SIM/eSIM or a phone’s personal hotspot.
Checking cellular data availability
Before setting up a connection, confirm your phone plan includes hotspot data, as sharing your phone’s connection draws from the same monthly allowance. On an iPhone, the feature that shares the cellular internet connection is called Personal Hotspot, and it can be shared with another iPhone, iPad, Mac, Windows device, and more.
For a Mac using Instant Hotspot, both devices must have Wi-Fi and Bluetooth turned on, be within 30 feet (10 meters) of each other, and meet minimum system requirements. If you plan to rely on a laptop with a built-in cellular modem, verify that your device has a SIM slot and that your carrier provides coverage in your area.
Connecting to cellular data on Windows
If your Windows laptop has a SIM card installed, you can manage the connection through the built-in cellular settings. Open Settings > Network & internet > Cellular, then select Use this SIM for cellular data to designate which SIM handles your connection. On Windows, the path Settings > Network & internet > Cellular > Use this SIM for cellular data is for managing the cellular SIM used for data.
For most laptops without a built-in modem, the simplest route is to connect to your phone’s hotspot. Apple documents three ways to connect a Windows device to an iPhone Personal Hotspot: Wi-Fi, Bluetooth, or a USB cable. For any of these, follow the manufacturer’s instructions for joining a Personal Hotspot.
- Turn on Personal Hotspot on your iPhone in Settings > Personal Hotspot.
- On your Windows laptop, open the Wi-Fi menu and select your iPhone’s name from the list of available networks.
- Enter the Personal Hotspot password if prompted.
To connect via Bluetooth, turn on Bluetooth on both devices, then on the iPhone go to Settings > Bluetooth and keep that screen open so the iPhone remains discoverable. On the Windows laptop, pair with the iPhone and confirm the connection. For a USB connection, use the cable that came with the iPhone or another cable that matches the ports on both devices, then plug the phone into the laptop.
Connecting to cellular data on Mac
On a Mac, the fastest way to use your iPhone’s cellular data is through Instant Hotspot. Click the Wi-Fi menu in the menu bar and choose your iPhone from the list. If both devices use the same Apple Account, the Mac connects directly; otherwise, enter the Personal Hotspot password.
You can also connect using Bluetooth or a USB cable. For Bluetooth, open System Settings > Bluetooth on the Mac, then open Settings > Bluetooth on the iPhone and keep it open. For Bluetooth on Mac, keep Bluetooth open on the iPhone so the iPhone is discoverable. When the iPhone appears on the Mac, select it. On Macs with macOS 12.5 or earlier, the path is Apple menu > System Preferences > Bluetooth.
For a USB connection, plug the iPhone into the Mac with the appropriate cable and trust the device when prompted. Note that Personal Hotspot uses the iPhone’s cellular internet connection only; it cannot share a Wi-Fi network that the iPhone is already joined to.
Managing cellular data usage
When your laptop is connected through a phone hotspot, all data usage counts against your phone plan’s allowance. Monitor your consumption on the laptop by checking the operating system’s data usage tools, but remember that the hotspot connection itself is billed through your mobile carrier.
To avoid overages, keep an eye on how much data you use during a session, especially for activities like video streaming or large downloads. For detailed instructions on checking data usage on your specific device, refer to your phone or laptop’s data management settings.
Frequently Asked Questions
How do I get personal hotspot on my iPhone?
To get personal hotspot, go to Settings > Personal Hotspot on your iPhone and toggle it on. If the option is missing, contact your carrier to confirm your plan supports hotspot data.
